Lefty Leverenz commented on HIVE-15448:
---------------------------------------
Doc note: This adds four configuration parameters which need to be documented
in the wiki.
* *hive.repl.cm.enabled*
* *hive.repl.cmrootdir*
* *hive.repl.cm.retain*
* *hive.repl.cm.interval*
* [Configuration Properties -- Replication |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-Replication]
Added a TODOC2.2 label.
(Grumbles: There's a minor error in the description of *hive.repl.cm.enabled*;
and 7 hours between +1 and commit doesn't give me enough time to find out about
new configs.)
